LEGAZPI CITY, Philippines— The Philippine Institute of Volcanology and Seismology recorded an ash explosion in Mayon Volcano early Wednesday, which caused ash fall in Albay towns located southwest and northwest of the volcano.
"The explosion, which occurred at around 1:58 a.m., is a clear sign of magma intrusion toward the summit crater of the volcano," said Alex Baloloy, Phivolcs science research analyst.
